CHARLES L. FREVERT, OF MINIER, ILLINOIS.

RAILWAY-TIE.

Specification of Letters Patent.

atented Dec. 21, 1909.

Application filed March 15, 1909. Serial No. 483,534.

To all whom it may concern.'

lle it known that I, CimnLns L. Fmcvnn'r, a citizen of the United States, residing at IViinier, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Railwayffies, of which the following is a specification.

This invention relates to improvements in reinforced concrete cement ties, and chair appliances, but more particularly that class of railway ties that are reinforced their entire length, and means for connecting the chairs to the reinforced portion of the tie.

This invention further relates to the means for tying the chairs together between the rails thereon.

This invention further relates to the removably secured side plates on the chairs and means for securing the same to theI chairs in combination with a tie bar.

This invention further relates to the serrations on the chairs and also the spring attachment to the bolts thereof.

lVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote corresponding' parts in the several views, in which:

Figure l, illustrates the device in a longitudinal vertical section exhibiting the reinforcing bar within the cement tie.v Fig. Q, illustrates a plan View of the device. Fig. 3, illustrates the metallic reinforcing bar detached from a tie. Fig'. LL, illustrates the tie bar in detail. Fig. 5, illustrates in section a chair and removably secured side thereof. Fig. illustrates the same device in plan view. Fig'. 7, illustrates in side elevation a chair and removably secured side with serrations therein. Fig. 8, illustrates in a sectional view enlarged a portion of the tie and reinforcing' bar with chair attached thereto by a bolt and spring' thereon.

This invention consists of a concrete railway tie A, provided with a reinforcing bar Ii. which is formed with ears I3, and bolt holes B3. This reinforcing bar is embedded in the cement tie, having bolts B2, attached thereto which extend upwardly for securing steel chairs on the top of a cement tie. The steel chairs referred to have ears C, on the outside thereof which are integral with the rib C2, and plate portion C. A removably secured side l), having' a rib (l, is attached to the plate of said chair C, through the medium of bolt. holes in those parts by bolts D. Said bolts also secure a tie bar E, to said removably secured side through the lnedium of bolt holes c, exteinliiig through the ends E', of said tie bar IC. This construction of railway cement ties otlei's greater resistance to the impact of cars as the reinforcing' bar ll, extends beyond the rails consequently the stress in the cement tie A, will extend the full length of the tie beyond said rails. The double ears C', give greater stability to the chairs C, in combination with the tie bar E, being connected directly to opposing chairs, independent of the tie A, as any undue strain on one side of a track will be minimized by the tie bar E, which will pull from the opposing side of the track, tlms dividing the strain between the opposing rails (l.

ln Fig. T, a modified form of securing the chair C, and removably secured side is indicated, the part C, having serrations C, and the other part I), having similar serrations D", said serrations preventing the parts from slipping when bolted together.

In Fig. S, a spiral spring l, is attached to the bolt B2, umler the nut thereon, which acts in a measure similar to a lock nut, as the least tendency for the nut to become disengaged from its accompanying bolt $2, would be checked by the resiliency of said spring' Il", as the spring maintains the same pressure against the nut when first secured thereon.

I do not limit my invention to the exact construction as herein indicated, as other devices may be employed and come within the scope of my device.

That which I desire to claim and secure by Letters Patent is:

l. A concrete cement railway tie provided with a reinforcing bar within said concrete cement tie, chairs on top of said concrete cement tie, bolts connecting said chairs to said reinforcing' bar, tie rods attached to said chairs, as specified.

2. A concrete cement railway tie provided with a reinforcing bar, ears on said reinforcing bar, bolts extending through said ears, said bolts attached to chairs, tie bars connecting said chairs, as specified.

3. A concrete cement railway tie, a reinforcing metal bar within said concrete cement railway tie, in combination with chairs, removably secured side plates on said chairs, tie bars attached to said chairs and removably secured side plates, as specified.

4. A concrete tie provided with a reinforcing bar embedded therein, chairs positioned on said tie, bolts extending throughV the chairs and reinforcing bar having Springs thereon, said chairs being formed in two parts, the lower parts having Serrations on their upper surfaces and the upper parts having serrations on their lower surfaces engaging with the serrations of the lower parts, and a tie bar bolted to the chairs and the reinforcing bar.

In testimony whereof I atix my signature in presence of two witnesses.
